Answer 1

\[a^2+b^2=c^2\\
\sqrt{a^2+b^2}=c\] so for the first one
\[\sqrt{9^2+11^2}=\sqrt{81+121}=\sqrt{202}\] others are similar

Answer 2

@satellite73 what would the equation be for seven and the square root of 140

Answer 3

the same idea
\[\sqrt{7^2+\sqrt{140}^2}=\sqrt{49+140}=\sqrt{189}\]

Answer 4

@satellite73 so I don't actually square the numbers are square roots?

Answer 5

@satellite73 so #3 equals B and #4 equals D right?
